  i need help in client server socket programming, both these programs are running successfully, and supposed to have communication wid each other,,but they dont.......i am using mirosoft visual studio 2010 for this project.

  SERVER SOCKET PROGRAM is,

  using System; using System.Net.Sockets; using System.Text;

  namespace ConsoleApplication1 { class Program { static void Main(string[] args) { TcpListener serverSocket = new TcpListener(8888); int requestCount = 0;

  TcpClient clientSocket = default(TcpClient); serverSocket.Start(); Console.WriteLine(" >> Server Started"); clientSocket = serverSocket.AcceptTcpClient(); Console.WriteLine(" >> Accept connection from client"); requestCount = 0;

  while ((true)) { try { requestCount = requestCount + 1; NetworkStream networkStream = clientSocket.GetStream(); byte[] bytesFrom = new byte[10025]; networkStream.Read(bytesFrom, 0, (int)clientSocket.ReceiveBufferSize); string dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom); dataFromClient = dataFromClient.Substring(0, dataFromClient.IndexOf("$")); Console.WriteLine(" >> Data from client - " + dataFromClient); string serverResponse = "Server response " + Convert.ToString(requestCount); Byte[] sendBytes = Encoding.ASCII.GetBytes(serverResponse); networkStream.Write(sendBytes, 0, sendBytes.Length); networkStream.Flush(); Console.WriteLine(" >> " + serverResponse); } catch (Exception ex) { Console.WriteLine(ex.ToString()); } }

  clientSocket.Close(); serverSocket.Stop(); Console.WriteLine(" >> exit"); Console.ReadLine(); } } }

  AND CLIENT SOCKET PROGRAM IS,

  using System; using System.Windows.Forms; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Net; using System.Net.Sockets;

  namespace WindowsApplication1

  {

  static class Program

  {

  [STAThread]

  static void Main()

  {

  Application.EnableVisualStyles();

  Application.SetCompatibleTextRenderingDefault(fals e);

  Application.Run(new Form1());

  }

  }

  }

  public partial class Form1 : Form { System.Net.Sockets.TcpClient clientSocket = new System.Net.Sockets.TcpClient();

  public Form1() { InitializeComponent(); }

  private void InitializeComponent() { this.textBox1 = new System.Windows.Forms.TextBox(); this.label1 = new System.Windows.Forms.Label(); this.button1 = new System.Windows.Forms.Button();

  this.SuspendLayout(); this.button1.Location = new System.Drawing.Point(160, 221); this.button1.Size = new System.Drawing.Size(129, 23); this.button1.Name = "button1";

  this.button1.TabIndex = 0; this.button1.Text = "click here to send data to server"; this.button1.UseVisualStyleBackColor = true;

  // // textBox1 // this.textBox1.Location = new System.Drawing.Point(15, 30); this.textBox1.Multiline = true; this.textBox1.Name = "textBox1"; this.textBox1.Text = " client started"; this.textBox1.Size = new System.Drawing.Size(268, 181); this.textBox1.TabIndex = 1;

  this.label1.Location = new System.Drawing.Point(9, 9);

  this.label1.Name = "label1"; this.label1.Size = new System.Drawing.Size(37, 13); this.label1.TabIndex = 2; this.label1.Text = "Client Socket Program - Server Connected ..";

  this.label1.AutoSize = true;

  this.ClientSize = new System.Drawing.Size(292, 266); this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;

  this.Controls.Add(this.button1); this.Controls.Add(this.label1); this.Controls.Add(this.textBox1);

  this.Name = "Form1"; this.Text = "Form1";

  this.ResumeLayout(false); this.PerformLayout();

  } private void button1_Click(object sender, System.EventArgs e)
